Abstract
A method in a cellular communication network comprising the following steps: marking a SIM card as dormant when said SIM card has not been used for at least an observation duration, provisioning a release node by backing up managing parameters related to said dormant SIM card, in a database, de-provisioning relevant managing nodes by removing managing parameters related to said dormant SIM card, redirecting any attachment request emanating from said dormant SIM card to the release node.
